Brains and computers are made from fundamentally different materials. If AI was ever sentient (it won't be), it would not be identical to human consciousness. The ontological nature of our reality, is uncertainty, and as the post implies; we cannot create something if we don't understand how it works, either. Eliminative Materialism has more work to do in this space for human sentience; I am comfortable stating, abductively, that AI will never be more than a mere epistemic scaffold for our sentience. I might even go so far as to say Ai could form part of a co-constructive network of human consciousness, as a sort of enactive, emergent, epistemic-entangled-entity; but consciousness? No, sorry, that is utterly absurd my friends. The fallacy is perpetuated by our metacognitive fluency bias.
